0780-0939 - Victor VTS700E-540 Heavy Duty Two-Stage Oxygen Regulator

Heavy-Duty Precision for Industrial Gas Control

The Victor VTS700E-540 Regulator (SKU: 0780-0939) represents the gold standard in heavy-duty gas control equipment. Part of the renowned VTS 700 series, this two-stage regulator is engineered for applications requiring precise and constant delivery pressure, regardless of fluctuations in the inlet pressure. As a high-pressure oxygen cylinder depletes, the output pressure of single-stage regulators tends to rise, requiring constant manual adjustment. The VTS700E utilizes a two-stage reduction mechanism to eliminate this issue, providing a stable flow rate from a full cylinder down to the empty mark.

Constructed with the industrial environment in mind, the regulator features a forged brass body and housing cap, offering superior resistance to wear, corrosion, and impact. The internal mechanism includes a stem-type seat and a stainless steel diaphragm (in the second stage) or high-strength neoprene, designed to withstand the rigors of daily use. The unit is equipped with a CGA 540 inlet connection, making it compatible with standard industrial oxygen cylinders. Safety is paramount in the design, evidenced by the external self-reseating relief valve which protects the regulator and downstream equipment from over-pressurization.

Operational ease is enhanced by the large, 2.5-inch brass gauges that provide clear readings of both cylinder and delivery pressure. The adjustment knob is designed for smooth operation, utilizing a Delrin cap bushing to reduce friction and wear. With a maximum inlet pressure rating of 3000 PSIG and a delivery range optimized for heavy-duty cutting and heating (typically up to 125 PSIG), the VTS700E-540 is the professional's choice for reliability and performance in shipyards, fabrication shops, and construction sites.
